GLSA-200806-10 : FreeType: User-assisted execution of arbitrary code
High Nessus Plugin ID 33246
SynopsisThe remote Gentoo host is missing one or more security-related patches.
DescriptionThe remote host is affected by the vulnerability described in GLSA-200806-10 (FreeType: User-assisted execution of arbitrary code)
Regenrecht reported multiple vulnerabilities in FreeType via iDefense:
An integer overflow when parsing values in the Private dictionary table in a PFB file, leading to a heap-based buffer overflow (CVE-2008-1806).
An invalid free() call related to parsing an invalid 'number of axes' field in a PFB file (CVE-2008-1807).
Multiple off-by-one errors when parsing PBF and TTF files, leading to heap-based buffer overflows (CVE-2008-1808).
A remote attacker could entice a user to open a specially crafted TTF or PBF file, possibly resulting in the execution of arbitrary code with the privileges of the user running an application linked against FreeType (such as the X.org X server, running as root).
There is no known workaround at this time.
SolutionAll FreeType users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose '>=media-libs/freetype-2.3.6'
